It’s almost the same as the default one, don’t forget to add as many media_dir as you need, set your friendly_name (the name your Xbox will see your pc), and most important, the presentation_url, otherwise pc will not be visibile from the Xbox (set it as your pc ip:port)

Start it and enjoy, your shares will be visible to your Xbox 360!

sudo /usr/sbin/minidlna

It will start in daemon mode (you can use the -d flag to debug if you have issues).

If you need to start MiniDLNA automatically at each boot, do the following:

Go to System -> Preferences -> Startup Applications, click Add, and use these settings:

Name: minidlna
Command: /usr/sbin/minidlna

Confirm, and MiniDLNA will start at each boot 🙂

Update: Version 1.0.16.3 added support for storing the db in a directory different than the default /tmp, so that informations will not be removed after each reboot (variable db_dir in the minidlna.conf)!
